Self-adaptive pier anti-collision device
The invention belongs to the technical field of bridge pier collision prevention, and discloses a self-adaptive bridge pier collision prevention device which comprises multiple stages of collision prevention assemblies and an air bag which are sequentially connected to a bridge pier in a sleeving mode from top to bottom. The multi-stage anti-collision assembly comprises an anti-collision inner sleeve connected to the pier in a sleeving mode, the two ends of the anti-collision inner sleeve extend outwards to form limiting parts, and an air bag is fixed to the limiting parts at the bottom end of the anti-collision inner sleeve; the anti-collision inner sleeve is sleeved with the anti-collision outer sleeve, the anti-collision outer sleeve is rotationally limited between the two limiting parts, a second-stage buffering assembly is arranged in the anti-collision outer sleeve, and a third-stage buffering assembly is arranged between the anti-collision outer sleeve and the anti-collision inner sleeve; the first-stage buffering assembly is connected to the outer side of the anti-collision outer sleeve in the circumferential direction, the first-stage buffering assembly is used for reducing radial impact force generated when a ship collides with the pier and decomposing the reduced radial impact force into radial component force and axial component force, the second-stage buffering assembly is used for reducing the axial component force, and the third-stage buffering assembly is used for reducing the radial component force.
本发明属于桥墩防撞技术领域，公开了一种自适应型桥墩防撞装置，包括由上至下依次套接在桥墩上的多级防撞组件和气囊；所述多级防撞组件包括：套接在桥墩上的防撞内套，且防撞内套的两端均向外延伸形成有限位部，气囊与防撞内套底端的限位部固定；套接在所述防撞内套上的防撞外套，所述防撞外套可转动的限定于两个限位部之间，且所述防撞外套的内部设有二级缓冲组件，防撞外套与防撞内套之间设有三级缓冲组件；沿周向连接于所述防撞外套外侧的一级缓冲组件，且一级缓冲组件用于降低船舶撞击桥墩时的径向冲击力、并将降低后的径向冲击力分解为径向分力和轴向分力，二级缓冲组件用于降低轴向分力，三级缓冲组件用于降低径向分力。
